Discoverer: well-known to old civilizationDiscovery Location: UnknownDiscovery Year: UnknownName Origin:Latin: cyprium (island the Cyprus well known for its copper mines).Abundance that Copper:Earth"s Crust/p.p.m.: 50Seawater/p.p.m.: Atlantic Suface: 0.00008Atlantic Deep: 0.00012Pacific Surface: 0.00008Pacific Deep: 0.00028Atmosphere/p.p.m.: N/ASun (Relative come H=1E12): 1.15Sources that Copper:Pure copper occurs rarely in nature. Usually copper found in together minerals as azurite, malachite and bornite and in sulfides together in chalcopyrite (CuFeS2), coveline (CuS), chalcosine (Cu2S) or oxides choose cuprite (Cu2O). Copper is obtained by smelting, leaching and also by electrolysis. Annual world manufacturing is around 6,540,000 tons. Primary mining locations are in USA, Zaire, Zambia, Canada, Chile, Cyprus, Russia and Australia.Uses that Copper:Most often used as an electrical conductor. The alloys are used in jewelry, copper sculptures and also for coins. The skin that the Statue of Liberty is make of copper.Additional Notes:Copper is a an extremely interesting element. It is one of the change elements that actually uses electrons from among the within orbitals in chemistry reactions. In addition, that has an ext than one oxidation state. Like many of the transition elements, copper has a colored ion. Copper frequently forms a bluish green solution. Copper (Cu) has two valences Cu i (cuprous) has one valence electron and Cu II (cupric) has actually two valence electrons. Copper was among the earliest recognized metals, having actually reportedly been mined for over 5000 years. In nature it has actually two isotopes, 63 (69.09%), which has actually 29 electrons and protons and 34 neutrons, and 65 (30.91%), which has 29 electrons and also protons and 36 neutrons. Brass and also bronze room alloys the copper.
